What This Code Means
D23.5 is the ICD-10-CM diagnosis code for other benign neoplasm of skin of trunk. A benign (non-cancerous) skin growth on the trunk of the body, including the chest, back, abdomen, or buttocks. D23.5 sits in the ICD-10-CM chapter for neoplasms (c00-d49), within the section covering benign neoplasms, except benign neuroendocrine tumors (d10-d36).
D23.5 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Trunk includes anterior and posterior chest, abdomen, back, and buttocks; document specific location when possible.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for D23.5 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Trunk includes anterior and posterior chest, abdomen, back, and buttocks; document specific location when possible
- •Ensure the lesion is confirmed as benign and not a malignant melanoma or other skin cancer
Excludes 1, Do NOT code together
- benign neoplasm of anus NOS (D12.9)
